Reduction of the Intersubband Scattering Delta Doped Layers by the Lorentz-Force of an In-Plane Magnetic Field

Abstract

In structures with a narrow delta doped layer we observe a strong anisotropy in the magnetoresistance when the current is applied either parallel or perpendicular to the in-plane magnetic field. This anisotropy is absent in structures with thick doping layers. By a detailed analysis of the solution of the Boltzmann transport equation we were able to show that the anisotropy is due to a reduction in the intersubband scattering. The reduction of the intersubband scattering is due to the fact that the Lorentz-force pushes electrons, which move perpendicular to the in-plane magnetic field direction. away from the layer of ionized impurities.
